Actually, it depends on your variety of hydrangea whether you can cut it back or not and still get blooms. Some bloom on old wood (from the previous season), some on new wood (from this season), and some on both. The common white snowball-type hydrangea in the north, Annabelle, blooms on new wood. Many of the larger and more decorative hydrangeas bloom on old wood so cutting those back means they won't bloom the next season. Newer varieties of hydrangeas bloom on both old and new wood.
I love hydrangeas, but have a difficult time getting them to bloom because I live in a cold, windy location. I keep trying different varieties/methods/locations to get success.

We got an inch of snow yesterday and have snow flurries today!!! I am so sick of winter, I'm ready to scream!!!
I keep telling myself I should be glad we're not getting that but it just doesn't work.
Hey, it's not like I'm some transplant from "up north" saying I get to plant stuff before you do. I'm from here! This is normal for me! Well, actually, I'm originally from a couple hours south where I would get to plant stuff even earlier! 





They even managed to get into one of my asparagus beds
